Allowed with quite a lot of restrictions, for the simple reason that a Yoriki is not a LPI or BPA carbon copy. He is only one step removed from the Imperial Court, and commands an authority way above what a Bretonian baton-twirling copper or a Liberty rent-a-cop can ever dream of - no matter how high placed in their respective services.
Besides, the very creation of this faction would remove one KSP gunboat from Kusari space, as I would cease to use the Tachikaze in favour of a fighter for day-to-day patrols. Also, the maximum number of gunboats would be a grand total of two, to start with, and only increase if the KSP expands beyond ten members.
